It's really a good trading tool. Stock selection, choose a stock with a box structure, and check the related announcements of this stock in advance (to avoid excessive fluctuations). 2. Preset the grid interval. As shown in the figure above, the price has been fluctuating within this range, so my grid will be set at 110-145. Highlight that the grid does not entrust orders. If it breaks through, it's not suitable for grid trading. 3. The benchmark price depends on the latest trading price at the start of the grid, which varies based on personal settings. I prefer to enter the market directly based on the day's market conditions. Anyway, the benchmark price will keep changing later...
